To find out how far the truck could drive with 7 gallons of gasoline, we can set up a proportion:

120 miles / 5 gallons = x miles / 7 gallons

Cross-multiplying, we get:

5 * x = 120 * 7

x = (120 * 7) / 5

x = 840 / 5

x = 168 miles

Therefore, the truck could drive 168 miles with 7 gallons of gasoline.
